Mars Mapper 2022 creates a representation of the Red Planet for any date & time between 1 November and 15 January 2023. You may choose albedo maps based on CCD imagery of the 2020 opposition by Martin R. Lewis, or colourised hand-drawn maps from 2021 by Makoto Adachi (ALPO-Japan). Either may be shown with or without labels. Note that the app doesn't show the changing shape of Mars' polar caps, the planet's phase, changing axial tilt, or the presence of clouds.

How to use Mars Mapper 2022

If you wish to display Mars for a specific date (day/month/year format) and time, enter the desired values and click the 'recalculate' button. Mars Mapper 2022 uses 24-hour format Universal Time (UT) synonymous with GMT.
